Title: Allotter/translator for a space information and reservation system
IPC: G08B5/22
Filed: 1960-01-22
Abstract: 938,172. Reserving seats &c. STANDARD TELEPHONES & CABLES Ltd. Jan. 22, 1960 [Jan. 29, 1959], No. 2393/60. Class 106 (3). The storage space of a magnetic allotter drum 10, for use in a system such as described in Specification 910,471, is divided into groups each of two successive angular positions 0-1, 2-3, ..., 998-999, Fig. 3. In the first (even) angular position of each group the respective request address (the subsidiary flight chart number, column number and the start and destination station numbers) and the search address (master airline chart) corresponding thereto are recorded in parallel. For example, in angular position 4 the request address 312/7 (i.e. subsidiary airline chart numbered 317 column 7) is recorded in parallel with the corresponding search address 171/2 (i.e. master airline chart numbered 171 column 2). The second (odd) angular position of each group is divided into nine cells corresponding to the maximum of nine stations of the flight column in the associated request address, the numbers recorded being those which the corresponding stations have in the search address. Thus, in the example quoted, column 7 of subsidiary chart 317 has entries in the first five rows only and these station numbers correspond to the station numbers (rows 1, 2, 3, 5, 6 on the master chart 171/2, which numbers are recorded in angular position 5 in the the cells 1<SP>1</SP> . . . 5<SP>1</SP>. In operation, when a flight availability request is received at the central station from an operator's position 12, Fig. 2, all the request addresses on the allotted drum 10 are read during one complete rotation of the drum and successively compared at 11 with the request address keyed in by the operator 12. Assuming as in the example above quoted, that the keyed in request address is 312/7 and includes the start and destination stations numbered 2, 4, then as the desired request address at angular position 4, Fig. 3, on the allotter is identified in the comparator, the associated search address 171/2 is read out and stored in buffer store 13 and the contents of the storage cell 2<SP>1</SP>, 4<SP>1</SP> in angular position 5, namely the station numbers 2, 5 are next read out and also stored at 13. This information is then used for deriving the answer to the availability request from the information storage device which stores only the information related to master air line chart.

Title: Synthetic non-cellulose filamentary material adapted for paper making, and the manufacture of paper therefrom
IPC: D01F6/18
Filed: 1962-01-26
Abstract: A filamentary material suitable for paper-making is made by wet-spinning a synthetic noncellulosic filament-forming polymer and stretching the wet-spun gelled filaments to the point of incipient breakage (i.e. to the point where breakage of at least one filament of the strand is apparent).  Polymeric materials preferred include polyacrylonitrile and acrylonitrile copolymers with up to 15% of the other monomer and having a molecular weight of 30,000-200,000, preferably about 60,000-80,000, but polymers containing only 35%, preferably more than 50%, combined acrylonitrile may be used.  A long list of suitable comonomers is given.  Other polymers which may be used instead of polyacrylonitrile include vinylidene halide, e.g. chloride and fluoride homopolymers and copolymers, after-chlorinated polymers, e.g. after-chlorinated vinyl and vinylidene homopolymers and copolymers, copolymers of vinyl halides e.g. vinyl chloride, and vinyl fluoride, with vinyl esters e.g. vinyl acetate and vinyl propionate, and polyvinyl alcohol.  The spinning solvent is suitably a concentrated aqueous solution of a water-soluble salt yielding highly hydrated ions in aqueous solution.  Examples include the preferred alkali-metal thiocyanates, especially sodium thiocyanate, zinc and calcium chlorides, lithium bromide, cadmium bromide and iodide, zinc thiocyanate, aluminium and calcium perchlorates, calcium and zinc nitrates, guanidide thiocyanate, and its mono and di-(lower alkyl) substituents.  Alternatively dimethyl formamide or other organic solvents may be used.  An aqueous coagulating bath at from -5 DEG C. to 30 DEG C., preferably containing a salt yielding highly hydrated ions, e.g. a thiocyanate, may be used.  Desirably the gelled filaments contain at least 50% water before they are stretched. Stretching may be from 14-16 times the original length of the filaments, and may be effected in a single stage, suitably by hot-stretching e.g. in water at 98 DEG C., or in a plurality of stages, suitably a cold solvent stretch (effected in air at room temperature immediately after coagulation) followed by a hot stretch. The filamentary material so obtained is cut into discontinuous paper-making lengths, refined in aqueous suspension to effect fibrillation, the fibrillated material sheeted to form a water-laid web, and the web heated to a suitable temperature to effect heat-bonding and drying e.g. at 65 DEG C.-120 DEG C.

Title: A method and apparatus for scanning
IPC: G11B27/10
Filed: 1963-01-25
Abstract: 958,473. Sensing records. FMA Inc. Jan. 25, 1963 [Nov. 5,1962], No. 3303/63. Heading G4M. Columns of a coded area 12, for example on a photographic film strip, are scanned in succession by a beam of light from a cathode-ray tube, scanning of a column being stopped short unless a column identifying mark 15 is sensed. The width of marks 15 is less than that of the data bits so that a scan traversing a mark 15 remains on the associated column for the remainder of the scan. By this method, time is not wasted in scanning empty columns. Each frame of film includes an image area 11, Fig. 1 and is marked by a frame bar 14. In scanning a column, the output of a photomultiplier associated with the scanning beam is examined at a predetermined time after a frame bar 14 is detected, and if the beam is not passing over a column mark 15 at this time, the C.R.T. beam is blanked off and returned to its quiescent position. The time interval is measured by means of a clock pulse source synchronized with the scanning speed and producing pulses at 1-bit intervals starting with bar 14. When the scanning beam does pass over a column mark 15, scanning continues over the two 7-bit characters in the column, these being separated by bars 13a, 13b. A modulus 7 counter is supplied with the clock pulses while the first character is being scanned, is inhibited from counting while bars 13a, 13b are being scanned and the clock pulse source is being re-synchronized, and then commences counting again while the second character is scanned. When the counter is filled for the second time the scanning beam is returned to its quiescent position. The output of the counter is used in conjunction with the photomultiplier output to identify the separate code bits. The system may be used in selecting a particular frame 11 for inspection.

Abstract: 648,792. Thermal ammeters. JAGERSBERGER, A. Feb. 4, 1948, No. 3315. Convention date, Feb. 4, 1947. [Class 37] [Also in Group XI] A pyrometer lamp for optical temperature measurement comprises a filament 5 which is stressed laterally by a thin wire 8 attached to it at a point 7 and connected at the other end to a fixed supporting frame 2, the wire 8, in turn, being connected intermediate its ends to a thin upwardly-extending wire 10 which passes around a pivoted roller 11 carrying a reflector 13 and is connected to one end of a tensioned spring 12. The expansion of the filament when heated to incandescence produces a deflection of the reflector which is measured with the aid of an external light source 14 and scale 16, the filament current being adjusted until the brightness of a part 6 of the filament is equal to that of the radiator under test. To compensate for error due to differences in the coefficients of expansion of the wires and the supporting frame, the latter, or parts thereof, may be made of an appropriate steel. The bulb may be filled with a gas of good heat conductivity, such as hydrogen, to accelerate a stationary temperature condition in the lamp.
